The Soldiers’ Masks Were Inspired by an Ant Colony
Director Dong-hyuk was inspired by an ant colony while coming up with the design of the soldiers’ uniforms. To that end, he gave the masks different designations. For example, some had a circle, which represented the worker drones while others had a triangle which represented the soldiers, but the square represented the managers within the group.
On the show, the managers, workers, and soldiers all have specific duties to perform and cannot deviate from those tasks. If they do, they’ll suffer the same fate as the contestants who fail a challenge.
